Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 7,237,895, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 7,237,895 | |
| -1 | -7,237,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,237,895.
Example:
1 x 7,237,895 = 7,237,895
and
-1 x -7,237,895 = 7,237,895
Notice both answers equal 7,237,895
With that explanation out of the way, let's continue. Next, we take the number 7,237,895 and divide it by 2:
7,237,895 ÷ 2 = 3,618,947.5
If the quotient is a whole number, then 2 and 3,618,947.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,237,895 | |
| -1 | -7,237,895 |
Now, we try dividing 7,237,895 by 3:
7,237,895 ÷ 3 = 2,412,631.6667
If the quotient is a whole number, then 3 and 2,412,631.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,237,895 | |
| -1 | -7,237,895 |
Let's try dividing by 4:
7,237,895 ÷ 4 = 1,809,473.75
If the quotient is a whole number, then 4 and 1,809,473.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,237,895 | |
| -1 | 7,237,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 227 | 911 | 1,135 | 1,589 | 4,555 | 6,377 | 7,945 | 31,885 | 206,797 | 1,033,985 | 1,447,579 | 7,237,895 |
| -1 | -5 | -7 | -35 | -227 | -911 | -1,135 | -1,589 | -4,555 | -6,377 | -7,945 | -31,885 | -206,797 | -1,033,985 | -1,447,579 | -7,237,895 |
